Question

An experiment was set up with the circuit diagram shown in figure.

Given that R₁ = 10 Ω, R₂ = R₃ = 5 Ω, r = 0 Ω and E = 5 V.

The power dissipated in R₁ is ______.

विकल्प

• 2 W

• 2.5 W

• 3 W

• 4.5 W

Answer 1

The power dissipated in R₁ is 2.5 W.

Explanation:

Power = I²R₁

= (1/2)² × 10

= 2.5 W
